Attributes of the Derby database connection URL

You can supply an optional list of attributes to a database connection
URL. Derby translates these
attributes into properties, so you can also set attributes in a Properties object
passed to DriverManager.getConnection. (You cannot set those attributes
as system properties, only in an object passed to the DriverManager.getConnection method.)

Attribute name/value pairs are converted into properties and added
to the properties provided in the connection call. If no properties are provided
in the connection call, a properties set is created that contains only the
properties obtained from the database connection URL.

Note: Attributes are not parsed for correctness. If you pass in
an incorrect attribute or corresponding value, it is simply ignored. (Derby does provide a tool for
parsing the correctness of attributes. For more information, see the Derby Tools and Utilities Guide.)
